Is it possible to change the SN with ESDashboard original /ES DownG / Serial Bluetooth Terminal with the old DRV 121?
I mean change the first 4 Letters of SN for 20/25/30km/h (N4GE / N4GC / N4GS) hack, without using DRV777 and 126 with ES DownG.

Example i install ES DownG / Serial Bluetooth Terminal and config File .
Use my SN and change the first 4 Letters to N4GS to 30km/h hack and use the new SN for the "full reg command generator"
The Hex Code of my SN write in "Serial Bluetooth Terminal"

Work this?
I

Hello guys, thanks for the tutorial, but I’m definitly more stupid than you !

Can You, PLEASE, tell to us, when we need to push the power button and hold it, and we we can release the button.
The precise moments please ...

Sorry for my bad English :)

Or maybe make a tutorial like that :

- Press ON the scooter
- Press CONNECT on the app
Etc.

Thank You so much !

Hi, this works for me (Win10+ESx dashboard)

How-to:
• (if you don't have BLE555, swap your Max dashboard with your ESx dashboard)
• Connect your scooter in Ninebot-Flasher
• Load file DRV777.bin.enc
• Press the On/Off button on the scooter and keep the button from now on pressed
• Klick the new button “Flash” on the Ninebot-Flasher (you will see the flash-progress in % till DRV777 is complete installed)
• Copy the command: 5AA50E3D2002104E3447534431313131433132333451FC (for the serial number N4GSD1111C1234) and paste it into the command field of the Ninebot-Flasher
• Hit the button SendCmd. The serial number will change at once
Alternative use the full reg command generator (https://tools.scooterhacking.org/fullsncmd.php) to generate a custom command
(To work with CFW, your serial number must begin with N4GSD1111C)
• Load the file DRV126. Klick the new button “Flash” on the Ninebot-Flasher (you will see the flash-progress in % till DRV126 is complete installed)
• Release the On/Off button on the scooter
• Reboot the scooter and connect it to the Ninebot-Flasher again, the new serial number will appear
• put back your Max dashboard

Thank You, donne for me, but ... the scooter stay at 28km/h, not 30km/h

When the DRV126 is instal, can we make a CFW with the generator ? ( https://max.scooterhacking.org/ )
I tried with 33km/h, but the scooter stay at 28km/h ...

Do You know why ?

EDIT : Oh, I think it’s because the battery is at 54% , I will see when the battery is full

Another thing,

Why on Windows we need to use the line command : 3e2002104e34475344313131314331323334
And on Android : 5AA50E3D2002104E3447534431313131433132333451FC
?

It's the same S/N but not the same line command

EDIT : And another question : On Android, how can we check the S/N ? I didn't see the option

Thanks

Windows app adds frame headers and checksum to the payload whereas on android you send a raw frame.

EDIT: it turns out it does not. Just send the full command 5AA50E3D2002104E3447534431313131433132333451FC with ninebot flasher a few times even if the display shows error 19.

Hi,
I have a strange problem with Serial Terminal.
I change my SN with the full command generator.
Put the Hex in the Serial Terminal but it dont change my SN.
The green answer says 01 no write permission, right?

Im on DRV 1.2.1 and use a orig. ESx
With my Win10 PC and Ninebot Flasher i can change the SN SN without any Problems.

Lock and unlock dont Help.
